Mr. Justice Buchanan
delivered tbe opinion of the Court.
. ,Tbe case is pending on certiorari. Tbe writ bas been granted and argument allowed. It is a suit for dam[593]*593ages for personal injuries sustained while plaintiff, in the discharge of his dnties as a messenger for the Southern Express Company, was riding in an express car, part of a passenger train operated by the defendant railroad company. The train was wrecked, and the injuries to plaintiff resulted.
To the declaration averring the negligent operation of the train as the cause of the wreck and consequent injuries to plaintiff, the railroad company, by way of defense, interposed its plea of the general issue, and, in addition thereto, a special plea, as was its right under section 4637, Shannon’s Code. This special plea admitted that the defendant was a corporation and common carrier on and prior to the date of the injury to plaintiff, hut averred that on said date there was in force between it and the Southern Express Company a contract, by the terms of which it was agreed between the parties that the railroad company would furnish, for the use of the express company in the transaction of its business, ears to be hauled by the railroad company on its line, to be used for the transportation of express matter, and to be occupied by employees of said express company in charge of such express matter, such employees to be transported in said express cars free of charge by the railroad company, and that the express company should protect and hold harmless the railroad company from all liability that the railroad company might incur, or be under to the employees of the express company for [594]*594any injuries such, employees might sustain while being transported by defendant over its line, whether such injuries were caused by the negligence of the railroad company or its employees, or otherwise, and that pursuant to said contract the railroad company did furnish to the express company cars known as express cars, and one of these was occupied by plaintiff as express messenger at the time plaintiff sustained the injuries on which this suit is based; plaintiff being in said express car as custodian of express matter therein being transported. The plea then averred the execution by plaintiff of the contract, the material parts of which are set out on the margin of this opinion.1
To meet this special plea, plaintiff filed a replication in which it was averred that the said accident release was executed by him without consideration, inasmuch as he was at the time it was signed already in the employ of the express company, and was given no new or different contract of employment, and further that the contract was against public policy, and for this reason void. Other matters were averred in the replication which need'not be set out for reasons later appearing herein.
The company demurred to the replication. The trial judge sustained the demurrer. Plaintiff declined to plead over, whereupon his suit was dismissed, and he prosecuted his appeal.
[595]*595By the judgment of the court of civil appeals it was held that the replication was sufficient, and, accordingly, it reversed the judgment of the circuit court and remanded the cause for further proceedings.
The petition for certiorari seeks a review of the opinion and judgment of the court of civil appeals. Upon some questions made by the replication the opinion of the court of civil appeals was favorable to the railroad company and against the plaintiff. The latter has presented no petition for certiorari and no assignment of errors, and is therefore concluded by the rulings adverse to it made by the court of civil appeals on the points referred to above. See C., N. O. & T. P. R. Co. v. Brock, 132 Tenn. (5 Thomp.), 477, 178 S. W., 1116; Knight v. Cooley, 131 Tenn. (4 Thomp.), 21, 173 S. W., 435; Murrell v. Rich, 131 Tenn. (4 Thomp.), 378, 412, 175 S. W., 420; chapter 82, Acts of 1907.
The court of civil appeals was in error in its construction of the legal effect of the accident release contract. In the construction of contracts the object is to ascertain the intention of the parties, and the important question is what the contract means as a whole. Paige on Contracts, vol. 2, sec. 1112; Arbuckle v. Kirkpatrick, 98 Tenn. (14 Pick.), 221, 39 S. W., 3, 36 L. R. A., 285; 60 Am. St. Rep., 854. Courts will look to the nature of the subject-matter, the relation of the parties to the contract, and the object sought to be accomplished. Paige on Contracts, vol. 2, see. 1123. There is no need in this case to resort to extrinsic evi-[596]*596denee in the construction' of the contract. Its terms are wholly free from ambiguity.
The contract begins as an application for employment and contemplates a term in futuro, bnt the applicant does not ask for a term for any particular length of time. He is content that the company may have the right to terminate the future term at its pleasure, and he agrees to all of the terms thereinafter set out, and that all his representations are for the purpose of procuring employment with the company. He then makes certain representations about himself, and thereafter agrees to execute a bond for the protection of the company, and then affixes his signature to his application. The conclusion is irresistible that this application looked to a future employment as contra-distinguished from one which existed when the application was made, and it follows that a term existing when the application was made was extinguished by acceptance of the offer made by the applicant. Such acceptance ended the pre-existing employment, and initiated the new one contemplated by the application. This view is strengthened by other parts of the contract presently to be noticed. The next part of the contract is the accident release.
It is manifest that the words “have entered, or am about to enter,” in the first clause of the accident release part of the contract, are intended to cover, on the one hand, the case of an applicant who, at the time of his application, was in the service of the company under a former contract of employment, which the [597]*597applicant intended to come to an end by the acceptance of his offer to make a new contract, and, on the other hand, those words were intended to cover the case of an applicant who had not heretofore been employed by the company. The signature of the applicant affixed to this part of the contract completed his offer. The next and final part of the contract is the acceptance of the applicant’s offer by the company.
The signature of the company to the last portion of the contract ended the old contract and completed the hew one. Its signature was a definite acceptance of the offer of the applicant to enter into the new and to abandon the old contract relations. By this completed contract, in the absence of an averment in his replication of fraud practiced upon him by the express company in the procurement of the contract, the plaintiff is undoubtedly bound in law, whether he read the contract or not, at the time he affixed his signature thereto. Railroad Co. v. Stone & Haslett, 112 Tenn. (4 Cates), 348, 79 S. W., 1031; Railroad Co. v. Smith, 123 Tenn. (15 Cates), 678, 134 S. W., 866. Plaintiff stipulated for employment of a certain kind, and employment of that kind he received from the company. The consideration for the rights which he surrendered by the terms of the contract was the employment received, and the law does not allow that he shall deny the consideration, ignore his contract, and reassert and recover under his surrendered rights, after having enjoyed the benefits for which he contracted, and which he received, as the result of his contract.
[598]*598Upon the question of consideration, it is immaterial whether plaintiff stipulated for a term of service to he extinguished at the pleasure of his employer or at a fixed time in futuro. The material fact is that he received what he contracted for, and what he received was of value in the eye of the law. Our conclusion therefore is that the contract was binding upon him, unless public policy avoids it.
Therefore the next question is whether the relationship of common carrier and passenger existed between the railroad company and plaintiff at the time he sustained his injuries. Many State courts of last resort had answered this question in the negative in passing upon eases involving facts and contracts like this, or closely analogous to it, prior to the decision in Baltimore & Ohio S. W. Ry. Co. v. William Voight, 176 U. S., 498, 20 Sup. Ct., 385, 44 L. Ed., 560. The question was also answered in the negative in the case last named. The contract involved in that case was in substance the same as the one involved here, and there, as here, the action was by an express messenger, and against a railroad company. The question certified in that case, after stating the material facts and the terms of the contract, was as follows:
“Does said railroad company assume, towards such express messenger while being carried in the course of his said employment in one of said express ears attached to a passenger train of said railroad company, pursuant to the contracts aforesaid, the ordinary liability of a common carrier of passengers for hire so [599]*599as to render said railroad company liable as such to said express messenger, notwithstanding the contracts aforesaid, for injuries he might sustain by reason of a collision between the train to which said express car is attached and another train of said railroad' com- - pany, caused by the negligence of employees of the railroad company?”
The opinion of the court, after referring to New York C. R. Co. v. Lockwood, 17 Wall., 357, 21 L. Ed., 627; Grand Trunk R. Co. v. Stevens, 95 U. S., 655, 24 L. Ed., 535; Liverpool & G. W. Steam Co. v. Phoenix Ins. Co., 129 U. S., 397 (9 Sup. Ct. 469); 32 L. Ed., 788 — held that while the principles declared in the cases above referred to were salutary, and the court had no disposition to depart from them, yet it was not to be forgotten that the right of private contract was no small part of the liberty of the citizen, and that the usual and most important function of courts of justice was rather to maintain and enforce contracts than to enable parties thereto to escape from their obligation on the pretext of public policy, unless it clearly appeared that such contracts contravened public right or public welfare. The opinion continues:
“It was well said by Sir George Jessel, M. R., in Printing & N. Registering Co. v. Sampson, L. R., 19 Eq., 465: ‘It must not be forgotten that you are not to extend arbitrarily those rules which say that a given contract is void as being against public policy, because, if there is one thing which more than another public policy requires, it is that men of full age and compe[600]*600tent understanding shall have the utmost liberty of contracting, and that their contracts, when entered into freely and voluntarily, shall be held sacred, and shall be enforced by courts of justice. Therefore yon have this .paramount public policy to consider; that yon are not lightly to interfere with this freedom of contract.’ ”
It was further said in the opinion that the agreements created a very different relationship between Yoight and the railway company from the usual one between passengers and railroad companies. It was pointed out that Yoight was under no stress as a passenger desiring transportation from one point to another on the railroad; that his occupation of the car especially adapted to the uses of the express company was not in pursuance of any contract directly between him and the. railroad company, but was an incident of his permanent employment by the express company and, said the opinion:
• ‘-He was on the train, not by virtue of any personal contract right, but because of a contract between the companies for the exclusive use of a car. His contract to relieve the companies from any liability to him, or to each.other for injuries he might receive in the-course of his employment, was deliberately entered into as a condition of securing his position as a messenger.”
The opinion then points out the distinction between the V.oight Case and the Lockwood Case.
What has been said about the case last commented on fairly indicates the view taken of the question by [601]*601decisions which had preceded that case, and by decisions which have followed it and approved its reasoning. Very elaborate notes discussing the cases on this subject will be found accompanying Denver & R. G. R. Co. v. Whan, 11 L. R. A. (N. S.), 432, and Coleman v. Pennsylvania R. Co., 50 L. R. A. (N. S.), 432.
The great weight of authority evidently supports the view that the relationship is not that of passenger and carrier in cases analogous on their facts to the present case and the Voight Case. In those jurisdictions where, under similar contracts and facts, a contrary ruling is found, it is generally rested upon some peculiar constitutional or statutory provision. An opinion by the supreme court of the United States approving the doctrine of the Voight Case is to be found in Santa Fe, Prescott & Phoenix Ry. Co. v. Grant Bros. Construction Co., 228 U. S., 177, 33 Sup. Ct. 474, 57 L. Ed., 787, and a later case by the same court is Robinson v. Baltimore & Ohio R. Co., 237 U. S., 84, 35 Sup. Ct., 491, 59 L. Ed., 849. In the case last named the contract involved was between the Pullman Company and one of its porters. The latter sued the railway company for injuries sustained while the porter was in the discharge of his duty on the Pullman car, resulting from a collision caused by the. negligence of the defendant. The defense was based on a contract between the porter and the Pullman Company similar in import to that under consideration in the present case. The court held it to be clear that unless the contract was condemned by statute it was valid, and [602]*602was a bar to plaintiff’s recovery, citing the Voight Case and Santa Fe, P. & P. R. Co. v. Grant Bros.Construction Co., supra. The statute relied on as destroying the validity of the contract was section 5 of the Employer’s Liability Act of April 22, 1908, 35 Stat. at L. 66, ch. 149 (U. S. Comp. St. 1913, sec. 8661), which provides that any contract, the purpose or intent of which shall be to enable any common carrier to exempt itself from liability created by this act, shall to that extent be void. But the court held that the Pullman porter'was not an employee of the defendant railroad company within the meaning of that statute, and it was also held that the relationship between the railroad company and the Pullman Company was not one of co-proprietorship, and on this point the opinion cites Oliver v. Northern P. R. Co. (D. C.), 196 Fed., 432.
Upon the foregoing authorities, we think it clear that the contract set up by the special plea was founded upon a sufficient consideration, was not opposed to public policy, and was a bar to the judgment sought by the plaintiff. The only case cited by the court of civil appeals to sustain its construction of the contract is Purdy v. R. W. & O. R. R. Co., 125 N. Y., 209, 26 N. E., 255, 21 Am. St. Rep., 736. In respect of the release which the baggageman in that case signed, the New York court, in its opinion, said:
“ ‘ He simply signed the contract, and the defendant kept on employing the plaintiff as baggageman;’ in other words, continued the already existing employment. ’ ’
[603]*603The language above quoted distinguishes the Purdy Case from the present one, for here, as we have held, the parties terminated the old and created a new contract, of which new contract the accident release was a part. The Purdy Case was referred to in a later New York ease. Runt v. Herring, 2 Misc. Rep., 105, 21 N. Y. Supp., 244. The court, in that opinion, said:
‘ ‘ The recital of the employment and the dollar paid distinguishes the case from Purdy v. Rome, etc., R. Co., 125 N. Y., 209 (26 N. E., 255, 21 Am. St. Rep., 736), and probably discloses a sufficient consideration to sustain the agreement. ’ ’
It results that the judgment of the court of civil appeals is reversed, and the judgment of the circuit court is affirmed.
